GUN-LOCKING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 792,381, dated June 13, 1905. Application filed November 26, 1904. Serial No. 234,325.

To all whom, it may concern.-

Be it known that I, MARTIN V. B. ALLEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gun-Locking Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved locking device for guns, but preferably to be used in connection with pistols or revolvers provided with the usual pivotally-mounted hammer and whereby the said hammer may be locked so that it cannot be drawn back from its initial position to either a half or a full cock and whereby said locking of the hammer against movement is permanent until the person desiring to use the same operates said locking device, releasing said hammer, a further object being to provide a locking device of this character for pistols or revolvers which is conveniently located in the handle thereof, where slight pressure may be exerted by the thumb to lock said hammer against movement and whereby a slight touch of the thumb-nail Will release said hammer when it is desired to use the pistol or revolver in the usual manner, a still further object being to provide such a locking device which is readily adapted to revolvers already in use or already on sale, said locking device being applied to the said revolvers by the simple drilling of two holes at right angles to each other in the handle member thereof and the insertion in these holes of spring-operated bolts constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a side view of a revolver provided with my improved locking device in operative position for locking the hammer thereof, said view being partially in section; Fig. 2, an enlarged view of a portion of said revolver and showing my improved locking device in a releasing position as regards the hammer of the revolver, and Fig. 3 a partial end view of the revolver and showing the ends of the members employed in said locking de vice.

In the drawings forming part of this specification I have shown a revolver provided with a handle portion a, a barrel 6, a rotatable cartridge-chamber 0, rotatably mounted on the barrel member 6 in the usual manner, and said barrel being pivotally mounted at (Z on the body portion (Z of said revolver, said body portion or being provided with the usual trig- 3 4 gor-guard (Z and trigger aand also mounted in said body portion (Z is the usual hammer (Z which is pivotally mounted at d, all of which is of the usual or any desired construction, and, as is usual in revolvers employing the hammer cl", said hammer is provided with a shoulder (Z at the rearward edge thereof, which engages the usual spring d mounted in the handle a.

Rearwardly of the hammer (Z and slightly below the shoulder (Z thereof I provide a recess or opening a, which is enlarged at its rearward end, as shown at 6 and a bolt 6 operates in the opening 6, and said bolt is provided with an enlarged head member 6 which normally projects slightly beyond the handle portion a, as clearly shown in Fig. 2, being held in this position by means of a spring 6, mounted in the enlarged portion a of the recess e, and the action of the spring 6 is always to force the bolt 0 backwardly or out of the recess a.

At the outer end of the recess 6, said recess being horizontally arranged in the handle a, I provide a vertical recess f, enlarged at its upper end, as shown at f and a bolt f 0perates in the recess f and is provided with an enlarged head f at its upper end, which operates in the enlarged portion f of the recess f, and the bolt f and head f thereof are normally forced upwardly by means of a spring f arranged in the portion f of the recess f, and the head f of the bolt f is provided with a shoulder f, which in the released position of the locking device engages a similar shoulder a on the head 6 of the bolt 6 said shoulder fl preventing the bolt 6 from being forced entirely out of the recess 0, and if pressure be exerted on the outer end of the head a of the bolt 6 said bolt is forced forwardly and into the body member (Z of the revolver, this operation being possible only when the hammer d5 is down or uncooked, and when the bolt 6 has been forced into the handle member a of the revolver a sufficient distance the spring f forces the bolt f upwardly until the head f* engages the shoulder e of the head 6 at which time the outer end of the head 0 is also engaged by the shoulder f of the head j, and the bolt 0" is thereby locked in the position shown in Fig. 1, and the hammer d cannot at this time be operated.

When it is desired to use the revolver or to cook the hammer (l thereof, pressure is eX- erted on the upper end of the head f 4 by means of the thumb-nail, said head being very small, and the bolt f is forced downwardly until the shoulder f thereof passes beneath the outer end of the head a of the bolt 6*, at which time the spring 6 forces the bolt 6* backwardly until the shoulder f of the head f' engages the shoulder a of the head e thereby preventing the entire removal of the bolt 6* and withdrawing the inner end thereof from the arc of movement of the hammer (Z and said hammer can at this time be cooked. It will therefore be seen that when carrying a revolver provided with my improved locking device the bolt 0 thereof is forced into the position shown in Fig. 1 and held in said position by means of the bolt f and when it is desired to use said revolver slight pressure on the bolt f releases the bolt 6*, and thereby the hammer (Z or if used by a soldier or policeman or other person in a hand-to-hand conflict and having no opportunity to use the weapon and in danger of losing the same he merely forces the bolt 6" inwardly, and the weapon is locked against use by his antagonist, as it requires a certain amount of practice to accurately locate the positions of the bolts in order to operate the same, and even though the said antagonist knew of the improvement on said weapon it would take him a moment or two to place the weapon in operative condition, and in this moment or two.

the soldier or policeman may have had an opportunity to save himself or recover the weapon, and while I have shown one of the bolts horizontally arranged and the other vertically arranged and the horizontal bolt passing beneath the shouldered end-of the hammer it will be evident that the direction of the movement of these bolts forms no part of the invention, nor does the exact point at which it is adapted to engage the hammer or any part thereof, as said hammer may be of various forms and may be provided with a recess or hole to receive the bolt 6, and-various other changes within the scope of my invention may be made, and, with this reservation,

What I claim as new, and desire to secure by Letters Patent, is

1. Agun provided with ahamme1'-locl ,com prising a bolt movable toward and from the hammer and adapted to engage the hammer and prevent its backward movement, a spring operating to force said bolt out of engagement with the hammer, and devices for locking the said bolt against backward movement both when it is engaged with the hammer and when it is out of engagement therewith, substantially as shown and described.

2. A hammer-look for guns, comprising a bolt mounted rearwardly of the hammer and movable toward and from the hammer and adapted to engage the same so as to prevent its backward movement, a spring operating to force said bolt out of engagement with said hammer, a supplemental bolt movable toward and from the first-named bolt, and a spring for forcing the supplemental bolt toward the first-named bolt, said supplemental bolt being adapted to engage the first-named bolt when the latter is in engagement with the hammer and also when it is out of engagement with the hammer, substantially as shown and described.

3. A gun provided with a hammerlock,comprising a bolt mounted rearwardly of the hammer and movable toward and from the same and adapted to be forced into engagement with the hammer so as to prevent the backward movement thereof, a spring operating to force said bolt out of engagement with the said hammer, and a supplemental spring-operated bolt mounted at an angle to the first-named bolt and movable toward and from the same and adapted to engage said first-named bolt when the latter is in engagement with the hammer, substantially as shown and described.
